Description

[Detailed Description of the Invention] The present invention relates to a flush toilet device, and more particularly to one that can be used as a seat type by placing and fixing a seat body on the top surface of an existing flush Japanese-style toilet.

Conventionally, this type of flush toilet device shown in FIG. 5 has been described in Japanese Utility Model Application Publication No. 56-13186.

To explain this, the lower end opening of the ball part b1' formed on the seat body B' is a Japanese-style toilet.
Since it is located at the entrance of the saucer part a2' of A', when sewage and filth are discharged into the saucer part a2', the sewage that bounces back onto the back of the seat body B' and the rim a of the Japanese-style toilet bowl A.
4' Adheres to the inner surface and top surface.

These stains caused by sewage cannot be washed away with washing water, and cleaning cannot be done without taking the trouble to remove the seat body B', resulting in the problem of accumulation and odor generation.

Therefore, the present invention aims to solve the above-mentioned problems and to keep both the Japanese-style toilet bowl and the seat body clean, thereby preventing the generation of dirt and the accompanying odor.

The basic structure of this invention is that the opening at the lower end of the ball part is watertightly connected to the drain entrance of the existing Japanese-style toilet, thereby preventing the back of the seat body and the inner wall of the Japanese-style toilet from getting dirty. It is something to do.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The existing flush-type Japanese-style toilet A has a structure and form well known in this type of technical field, and the one shown in Fig. 1 has a saucer portion a2 at the rear of the interior and a tray portion a2 continuous to the tray portion A2 at the front of the interior. This is a so-called flushing type toilet in which a drainage channel entrance a1 is formed respectively, and a seat body B is placed above the Japanese style toilet A so as to cover it.

The seat body B is made of ceramic or synthetic resin such as FRP and has a shape that covers the upper surface of the Japanese-style toilet bowl A, and the front half of the seat body B is formed into a box shape with an open bottom, and the front cover part a3 of the Japanese-style toilet bowl A is formed. At the same time, a water supply chamber b4 is formed in a hollow shape on the upper surface thereof, and a ball part b1 facing the saucer part a2 of the Japanese style toilet bowl A is opened in the rear half part.

The ball part b1 is formed into a funnel shape along the rear part of the rim a4 of the Japanese-style toilet A, and its lower end opening is connected to the Japanese-style toilet A.
At the same time, a rim water passage b2 is provided at the upper end opening over the entire circumference.

The rim water passage b2 is located above the ball portion b1,
It is formed to protrude inward so as to face inside the ball part b1, and a number of water injection holes b3 are bored at appropriate intervals on its lower surface, and a communication hole b5 communicating with the water supply chamber b4 is bored therein.

Further, a cylindrical water channel b6 extending in the height direction is provided at the rear end of the ball portion b1, and a through hole b7 is bored at the upper end of the water channel b6 to communicate with the rim water channel b2. A water fountain b8 is formed at the lower end thereof and opens toward the drain entrance a1 of the Japanese-style toilet bowl A.

A connecting pipe 1 is provided at the lower end opening of the ball portion b1.
Connect.

The communication pipe 1 has a flange portion 2 at its upper end that connects to the lower end opening of the ball portion b1 and the water fountain b8,
The middle part is bent along the saucer part a2 of the Japanese-style toilet bowl A, and the lower end is inserted and connected to the drain entrance a1 of the Japanese-style toilet bowl A, and both are sealed water-tightly by the sealing material 3.

Further, a water reservoir portion 4 is recessed on the lower surface of the inner circumference of the communication pipe 1.

Therefore, the lower end opening of the ball part b1 and the Japanese-style toilet A
It communicates with the drainage channel entrance a1 in a watertight manner.

On the other hand, a water supply chamber b4 formed on the upper surface of the front half of the seat body B has a water supply device C, which is a water source for supplying water to the so-called existing flush-type Japanese-style toilet A, such as a water storage tank and a flush valve, and in this embodiment, a hand-washing device. The tip of the cleaning pipe 5 connected to the secondary side of the water storage tank without a pipe is connected. A lid 6 is placed on the water supply port a5 of the Japanese-style toilet A, which was connected to the cleaning pipe connected to the water supply device C.
etc. and close it.

In addition, a mounting hole b9 is drilled in the upper surface of the seat body B, and a toilet seat 7 and a lid 8 are rotatably mounted above the seat 7 as needed in the hole b9, and a pedestal b10 is protruded from the lower end of the outer periphery. This pedestal b10 is fixed to the floor surface D using screws 9 or the like.

In such a flush toilet device, when a predetermined amount of flushing water is flowed from a water supply device C such as a water storage tank or a flush valve through the cleaning pipe 5 to the water supply chamber b4 of the seat body B, the rim is flushed from the communication hole b5. A part of the water flows into the water passage b2 and is discharged from the water injection holes b3 toward the inner circumferential surface of the ball portion b1 to wash away dirt adhering to the surface, and the remaining washing water flows into the water passage b6 through the water injection hole b7. The flow is discharged from the water spout b8 toward the water reservoir 4 of the communication pipe 1, and the waste on the water reservoir 4 flows to the drain entrance a1, passes through the trap portion a6, and is discharged from the drain outlet a7.

Next, what is shown in FIG. 3 is another embodiment, in which an existing flush-type Japanese-style toilet A has a saucer part a2 at the front of the interior, and a drainage channel entrance a1 connected to the saucer part a2 at the rear of the interior. In this case, the lower end opening of the ball part b1 formed on the seat body B is extended downward to create a Japanese-style toilet A.
It fits into the drainage channel entrance a1 and is sealed watertight with the sealing material 3.

Therefore, when a predetermined amount of cleaning water is flowed from a water supply device such as a tank or a flush valve to the seat body B through the cleaning pipe 5, it is discharged from the water injection hole b3 of the rim passageway b2 and sprays into the ball. The filth adhering to the inner surface of part b1 is washed away, and the filth in the drain entrance a1 and the trap part a6 is flushed out to the drain outlet a7.

In the above embodiments, the Japanese-style toilet A is installed on a stepped floor surface D that can also be used for men's errands, but the present invention is not limited to this. Needless to say, the same is true even in the case of a type in which a Japanese-style toilet bowl A is provided on a flat floor surface D.

The one in Figure 4 is the drain entrance a of Japanese-style toilet A.
1, after connecting a substantially S-shaped communication pipe 1 having a flange portion 2 at the upper end in a watertight manner, mortar or the like 10 is poured into the interior of the Japanese-style toilet bowl A to backfill it to form a surface 11 in a planar shape. After this surface 11 is hardened, the seat body B is installed, and the lower end opening of the ball portion b1 of the seat body B is connected to the flange portion 2 of the communication pipe 1.

Further, in the drawings, the ball portion b1 of the seat body B is provided with a water reservoir portion b11 having a very shallow water seal, but this may be omitted.

Since the present invention has the above configuration, it has the following advantages.

A rim water passage with many water injection holes for cleaning the inner surface of the ball is provided at the top opening of the ball, and the bottom opening of the ball is watertightly connected to the drain entrance of the Japanese-style toilet, so that the back side of the seat body The inner wall of the Japanese-style toilet bowl does not get dirty, it is easy to clean and can be kept clean, and unlike conventional toilets, there is no foul odor caused by dirt.
